Title: Auxiliary video data slicer
Inventor: RODRIGUEZ-CAVAZOS ENRIQUE
IPC: H04N7/025
Filed: 1993-01-14
Granted: 2002-10-15
Abstract: A data slicer for extracting auxiliary video data from a video signal adapts (212, 215) a data slicing level to the amplitude of the data signal as indicated by the average value of a run-in clock (RIC) signal that is included in the video signal. Control (200, 220, 250) of the slicing level occurs during a window interval (RICWND) that spans an integral number of cycles of the RIC signal. The presence of the RIC signal within the window interval may be verified (200, 220) as part of the slicing level ad-justment operation. The data slicer is suitable for implementation in a digital integrated circuit.

Title: Full shunt boost switching voltage limiter for solar panel array
Inventor: ASHLEY CHRISTOPHER R
IPC: G05F1/67
Filed: 1994-10-26
Granted: 1999-02-02
Abstract: According to the present invention a bus voltage limiter (10) is connected between a photovoltaic solar panel array (14) and a load (18) to limit the output voltage to a fixed dc reference voltage (V ref). The limiter includes a pulse width modulator (20) which controls the duty cycle of a power switch (22) from 0% to 100% to maintain a substantially constant output voltage V ref. A coupled inductor type boost DC to DC converter (26) includes a pair of main winding (26A,26B) which cooperate with the duty cycle modulated power switch to provide the output voltage.  An auxiliary winding (26C) provides input ripple current cancellation in conjunction with a second inductor (30) and a dc blocking capacitor (32).

Title: Outboard motor, and engine thereof
Inventor: TSUNODA MASAKI
IPC: F02F1/10
Filed: 1994-11-18
Granted: 1998-04-28
Abstract: An outboard motor body case is supported on a swivel shaft  through  a  connecting  member.  The  swivel  shaft vertically swingable about a tilting shaft. An engine is mounted at an upper portion of the outboard motor body case, with a crankshaft thereof being directed vertically, and  a  flywheel  is  mounted  at  a  lower  end  of  the crankshaft ant disposed between an engine block and the connecting  member.  A  dynamo  is  mounted  within  the flywheel, and a starter motor is engaged with a ring gear which is formed around an outer periphery of the flywheel.          Thus, since the flywheel having a large weight is mounted at the lower end of the crankshaft, the position of the gravity  center   of   the   outboard  motor   is   lowered.          Therefore,  it is possible to easily perform a tilting-up about  the  tilting  shaft  with  a  small  force.  Moreover, since the flywheel is mounted on a power taking-off side of  the  crankshaft,  the  torsional  vibration  of  the crankshaft can be reduced.

Patent CA-2148590-C (CA)
Inventor: GARFIELD NATHANIEL H
IPC: E04C5/12
Filed: 1992-11-05
Granted: 2001-05-29
Abstract: A method and an anchoring element for high strength solid wall anchoring in which a solid plastic plug is inserted in a hole in a solid wall of a porous material such as concrete. The invention provides a high strength compressive bonding between the plastic plug and the wall which simulates high strength chemical bonding.  In order to effect the high strength compressive bonding, the plug is inserted into a hole in the wall having nominally the same dimension as the plug. A screw of substantially the same diameter as the plastic plug is inserted into the plug to provide the anchoring. The plastic of the plug is an extrudible material such as polypropylene, high density polyethylene and co-polymers, which is extruded against and into the solid wall of the hole by the rotary insertion of the screw. Continued rotation of the screw causes a very high compression of the plastic between adjacent threads of the screw and a thin, very highly compressed film, which substantially covers the threads. The extrusion and the highly compressed areas of plastic provide phenomenally high resistance to pull-out of the plug from the wall. The plastic plug further contains one or more hairline separations or cleavages which serve to guide the screw into a path in the center of the plug to maximize the extent of the circumferential extrusion.

Granted: 2000-02-22
Abstract: A drag brake mechanism prevents rotation of the shaft of a truck mounted connect-disconnect, clutch-operated, power takeoff device when the clutch is in its disconnect mode, by applying a constant braking force to the shaft which cannot be overcome by inadvertent frictional forces within the discs of the clutch that may occur despite the clutch being in its disconnect mode.          The constant force selected, however, is insufficient to create undue heat during normal shaft rotation and is easily overcome when the clutch is placed in its connect mode.

Abstract: A method and apparatus for lateral alignment of a cross-direction profile control of a web as required in a paper-making process.   In the method, a certain cross-direction profile of a dried web, particularly the basis weight profile thereof, to be aligned is gauged.  A profile measurement signal thus obtained is passed to a control system of the paper machine which provides a control signal suited to control adjustment devices of the cross-direction profile control provision.  The web is provided with at least one marker line whose lateral shift or shifts is/are detected at the measurement point of the cross-direction profile of the dried web,  or in the vicinity thereof.   The detection of the lateral shift(s) is used to generate a measurement signal thereof which is employed to control the lateral alignment of the web profile adjustment provision.  The information obtained from the detected lateral shift(s) then used in the control of the lateral alignment of the consistency profile control provision adapted in conjunction with the paper machine headbox.  The marker agent used to make the marker line is injected to the stock at the inlet side of the stock feed channel to the paper machine headbox,  most advantageously close to the control valve set of the consistency profile control provision.
